Specification of Letters Patent. T Patented Dec. 24, 1912.

Application filed May 11, 1912. Serial No. 696,646.

Be it known that I, HENRY P. DE ZETTER, a citizen of the United States,residing at Byron, in the county of Genesee and State ,of New f York,have invented certain new .and useful Improvements in Separators, of

which the following is a specification.

' roun The object of this invention is to provide a machine forseparating various kinds of grains but more especially for separatingand grading beans. .That is separating the heavy, well formed beans fromthe light or poorly developed or mis-shaped beans and from' the smallstones, dirt, etc., with'which they may be associated or mixed. Thebeans referred to are the white beans such as-are used for soup orbaking which feed regulating device by which the feed of the beans tothe separating mechanism is controlled.

These and other objects of my invention will be full illustrated in thedrawings, de-

scribed in he'specification and pointed out in the claims-atthe endthereof.

In' the', accompanying drawings, Figure 1 lllustratesa front elevationof my improved separating machine as viewed from the right in Fig. 3.Fig. 2-is a side elevation of the duplexmachineconstructed according tomy invention. -Fig. 3 is a sectional elevation of m'y 'inachine whichsectionis taken on the line 3f-''3"" in Fig. 1. Fig. 4 is an enlargeddetail sectional view of the feed regulating mechanism section beingtaken-on the line 4"4" of Fig. 1. Fig. 5 is a longitudinal sectionthrough the machine shown in Fig. 2.

In the accompanying-drawings, like reference characters refer to'likeparts.

My improved separating machine consists of a framework 1 having therollers 2, 3 mounted therein at the upper and lower ends thereofrespectively. This framework is pivotally mounted at 5 on the legs 4 atthe lower end and is also pivotally mounted on the adjustable support 6at the upper end. This adjustable support has the threaded 'stem 7thereon which passes through the bracket 8 and is supported thereon bythe nut 9. By the turning. of the nut 9, the framework 1 can be swungaround the pivot 5 and any angular adjustment of the framework can besecured.

Mounted in the framework 1 is the separating table 10 and bet-ween therollers 2 and 3 passes the endless belt or apron 11, the movement ofwhich is indicated by the arrows shown in Fig. 3. This table controlsthe'middle section which is sufiiciently parallel to the long sides ofthe framework 1, above which is the upper section which slants towardthe horizontal and below which is the lower section which slants towardthe vertical and the pitch of the slope being decreased in the uppersection and being increased in the lower section differing in thisrespect from the pitch of the middle section.

Mounted on the framework 1 is the hopper 12 having the feed openings 13in the bottom thereof, each of which feed openings is controlled by thefeed regulator 14: which feed regulators are mounted on and rotate withthe shaft 15, such as is shown in Fig. 1. Each of these feed regulatorsis composed of a pair of disks 16 between which is placed a'wheel havingpocket-s or recesses 17 therein.- Fastened to the bottom of the hopper12 are the guards 18 which'bear against the wheel of the feed regulatorand prevent the beans or grain from working down back of the feedregulator and compel all of the materialto be separated-to ass over thefeed regulator onto the separating apron 11.

As shown in Figs. 3 and 4, the material to be separated is placed inthe'hopper 12 and that the sound heavy beans will roll down theintermediate portion of the table faster than the belt 11 is travelingupwardly thereon, so that such beans will rapidly approach the steeplyinclined portion of the table at the end thereof. When the sound beansreach the lower portion of the table, they will roll faster due' to theincreased steepness of the incline and pass ofi from the end thereofinto the chute 20."- The light or misshaped beans will not roll down asfast as the belttravels up and will be carried above the middle portionof the table 10 onto the u per end thereof which is less steeplyincllned, after which they will cease to roll at all and will be carriedup over it practically as fast as the: belt travels. They will pass overthe roller 2 and will be discharged into the chute 21 onto the table. Byraising or lowering the upper end of the frame 1, the proper incline ofthe table 10 can be secured by which the separating machine will workwith the most efiiciency and despatch.

In Figs. 2 and 5, I have shown views of the duplex machine. In thismachine all of the beans are dumped into a single hopper 25 at the top,from which they are fed into the hoppers 26 and 27 and pass therefromthrough the feed regulators 28 and 29 onto the belts 30 and 31 whichtraverse the separating tables 32 and 33. The heavy-beans are dischargedinto the spout 34 along which they are lined by the conveyer worm 3-5,while the light beans are discharged'into the chutes 36 and 37 at theopposite ends of the machine. The mac ine shown in Figs. 2 and 5 ismounted on t e base 38 on which are mounted the uprights 39, 40, 41 and42, from which the various parts of the machine are supported. On theseuprights are supported the upright frames 43 on which are mounted torun, a pairof cone pulleys 44 and 45. The pulley 44 is a driving pulleyried on the pulley 45 on the shaft thereof, are the pulleys for whichbelts run for driving the various parts of the machine. The belt 46 isused for driving the worm, the belt 47 for .driving the nearest feedregulating shaft from which in turn the farthest feed regulating shaftis driven by the cross-belt 48. The belt? 49 is also used for drivingthe nearest upper roller 2 and the cross belt 50 is used to convey thepower therefrom to the opposite roller 2. ,By shifting the belt 51laterally on the cone pulleys 44 and 45, any desired variation in thespeed for operating the machine may be secured. I

In the operation of my machine, the beans are dumped into the hopper andpass through the feed regulator 14 which .deposits them in small streamsupon the upwardly moving'belt. The heavy beans at once begin to rolldown the belt faster than the belt travels up while the light beans rolldown more slowly than the belt travels up or do not roll down at all.Thus the heavy beans soon reach the steep, inclined portion of the tableat the bottom thereof, while the light beans soon reach the upperportion of the table which is almost horizontal. The separation is thusquickly effected and the highgrade beans are deposited into the lowerchute while the low grade beans are carried into the upper chute.

Having thus described my invention, what I claim as new and patentableis as follows:

1. In a separating machine, the combination of an inclined table, a belttraveling up over the said inclined table, said inclined table havingthree grades of inclination thereon arranged progressively from top tobottom, the lightest inclination being at the top and the heaviestinclination at the bottom.

2. In a separating machine, the combination of a frame, a table securedtherein, a belt mounted to travel over said table, said table havingthree grades of inclination therein, the middle part of said tablehaving a moderate inclination, the upper part of said table having alight inclination and the lower part of said table having a heavyinlclination.

3. In a separating machine, the combination of a frame, a table securedtherein, a beltmounted to travel over said table, said table havingthree grades of inclination therein, the middle part of said tablehaving a moderate inclination, the ,upper part of :said table having alight inclination and the lower part of said tablehaving a heavyinclination, rollers at each end of said table,

.said belt traveling over said rollers and said table, a chute adjacentto each of said ;rollers.

and the pulley 45 is a driven pulley. Car- 4. In a separating machine,the combinasively from top to bottom, the lightest inclination being atthe top and the heaviest inclination at the bottom, said belt movingcontinuously in one direction and being adapted to receive unsortedgrain thereon and to separate it by the movement of the belt andinclination of'the table and dis- ;charge the sorted material at theopposite fends thereof.

5. In aseparating machine, the combination of an inclinedv table, anendless im-' pervious belt traveling up over said inclined table, saidtable having two grades of inclination thereon arranged progressivelyfrom top to bottom, the lighest in-' clination being at the top and theHeaviest inclination at the bottom, said belt moving In testimon whereofI aflixmy signature continuously in onedirection and being in presence 0two witnesses.

adapted to receive unsorted grainflthereon and to separate it into radesby the movement of the belt and inc ination of the table, and dischargethe different grades at the opposite ends thereof.
